Abstract:
Number notes are part of the art of music. Notation or number notation is used to
see musical tones with a certain frequency. This notation is written using numeric
symbols, such as the numbers 1 (one), 2 (two), 3 (three), 4 (four), and so on. Reading
numeral notation means reading written music and then playing it through musical
instruments or singing it into vocals. It is difficult to read and recognize symbols from
numeric character notation and convert them into audio which is a problem in itself. The
object recognition algorithm can be used to identify numeric notation objects in order to
make it easier for people to find out the number notation in music. Based on this study,
an application was built to convert notation number to piano sound by implementing
OCR with Logistic Regression using telegram bot. The process will be done in a telegram
bot where the user will be sending the picture of the notations, and the bot will send back
the result which has been integrated from the machine learning model that was executed
on the backend side. The system will help in converting the number of notations from a
picture or message sent on the telegram bot into piano sound format with Android-based.
